I don't understand the check for __e. 

If you continue, then neither __t nor __x change, the only difference is that
you sample a new __e. But __e doesn't have any effect in the value of __x, so
if(__t == __x), then __x is always returned, no matter the value of __e. I
maybe missing something, so take my words with suspicion.
